Enter these values into our torque calculator. It uses the torque equation: τ = r * F * sinΘ = 0.5 * 120 * sin(90°) = 60 Nm. The torque calculator can also work in reverse, finding the force or lever arm if torque is given. If you want to learn more about the concept of force and Newton's second law, try the acceleration calculator.
We have a rolling machine with 3 rollers; the bottom has two rollers with diameters of 168 mm and one top roller with a diameter of 219 mm. I want to calculate the required force to bend a 10 mm thick plate which is 2,500 mm wide. The rolling machine is connected to a 10 HP motor with a gear box and the rollers have an rpm of 8.

The presentation covers the different aspects of machines including unwinds, rewinds and point-to-point applications. It also looks at the different methods of control be it either speed or torque. Lastly we will explore the different types of tension systems including: manual, open loop and closed loop. We will discuss different components
In many applications, the load slides relative to a collar, thereby requiring an additional input torque T c: T c = F µ c d c / 2. Ball and tapered-roller thrust bearings can be used to reduce the collar torque. The starting torque is obtained by substituting the static coefficients of friction into the above equations.
